e it known that I, VJOHN'R. SQHRADER, a nited States, and residing in the city of New York, county of Bronx, and State of New York, haveinvented certain new and useful Improvements in Ma-' terial for Applying Lubricants to Axle- Bearings and Particularly to Journals of Railway Rolling-Stock, of which the following is a specification; a

his invention relates. broadly. to ma; terials used for V i ing employed in railroad locomotive and car axles. It is the object of this invention an improvement upon materials hitherto used or known for the purpose.

Many materials and devices have been invented for the purpose here contemplated, but it is a suflicient commentary upon their utility to draw attention to the fact that practically all railroads continue to use simple waste packing, the same being merely ordinary wool or cotton waste or a mixture of the two.

two and only two characteristics are requisite, 'viz., that it shall feed a sutlicient amount of oil or other lubricant to the journal or other bearing surface to adequately lubricate the same, and secondly, that-it shall not hold against bring into contact with other bearing surface any abrasive element, since if this is done it will tend to cause excessive wear, friction etc. Such abrasive elements may be of two classes, either the dust, cinders and the like naturally accumulated .during the operation, or some element such as 'metal or rough fiber contained in the packing itself. 7

The ordinary waste now in general use is deficient in both of these aforesaid essential characteristics since it quickly settles into a sodden mass, upon'the upper or contact surface of which foreign abrasive elements readily collect with the result that from the journal enthereby entirely failing to perform its function as a conveyer oflubricant to the bearing or it collects on its surface many foreign matters, holds them in contact with the journal or other bearing, thus causing undue friction and the dangerous and costly condition known as hot-box.

Experience has shown that could these Specification of Letters Patent. filed January 4, 191 Serial N o,

two diificultiesattendant upon the use of the other ing an abrasive element.

My experiments with various substances promptly forced g that the substance to be added must be vegetable in origin, absorbent and readily intermingle with the cordlike fibers of the waste. After failures with many different substances I found that these qualities were all present in sea grass, the

most satisfactory variety being that commercially known as Canadian sea grass.

I have found that this sea grass alone, will give more satisfactory results than any other known packing where the'strain is not too great, but for ordinary use I have found that in practice the best results are obtained when the sea grass is mixed with from one to four he manner in which this mixture operates may be briefly described as follows he sea grass being resilient and non-com-' pressible tends to hold up the waste and keep it in contact with the journal. The sea grass being highly absorbent also acts as a reservoir for the oil and feeds it to the waste in a manner similar to that in which oil is fed through a wick in a lamp. Being resilicut and non-compressible,-the sea grass also holds the waste fibers somewhat apart thus allowing air to circulate through the packing and likewise permitting foreign sub as dust and oinders to pass through the packing to the bottom of the journal-box. One additional advantage of the sea grass is worthy of note, viz., its :pol-

efforts have been made horn of the dilemma by introduc ishing quality, as a result of which a journal which has been for a short time in'contact therewith assumes a smooth and bright appearance.

I therefore claim- 1. A packing ior journal boxes consisting of a mixture of commercial cotton and wool waste and a fibrous resilient absorbent vegetable element.

2. A packing for journal boxes consisting of a mixture of commercial cotton and wool waste and a fibrous resilient non-abrasive vegetable element.

'3. A packing for journal boxes consisting of a mixture of commercial cotton and wool waste 7 and a fibrous resilient non-abrasive absorbent vegetable element.

at. A packing for journal ,boxes consisting of a mixture of'commercial cotton and wool Waste and resilient sea grass.

'6. A packing for journal boxes consisting of a mixture of 66%% of commercial cotton and wool waste and 33=-% of resilient sea grass.
